Package : xen
Version : 4.1.6.lts1-5
CVE ID : CVE-2016-10013 CVE-2016-10024
Multiple vulnerabilities have been discovered in the Xen hypervisor. The
Common Vulnerabilities and Exposures project identifies the following
problems:
CVE-2016-10013 (xsa-204)
Xen mishandles SYSCALL singlestep during emulation which can lead to
privilege escalation. The vulnerability is only exposed to 64-bit x86
HVM guests.
CVE-2016-10024 (xsa-202)
PV guests may be able to mask interrupts causing a Denial of Service.
For Debian 7 "Wheezy", these problems have been fixed in version
4.1.6.lts1-5.
We recommend that you upgrade your xen packages.
